When designing for desktop, what resolution do you guys use?
For example, I’m doing a redesign of all the font sizes on a website. I’ve designed it in 1920 x 1080, but the customer is viewing my prototype on a 1440 x 900 screen. I understand that they have the same ratio, so the prototype will shrink/grow to fit their window, but I assume the text sizes will also scale, meaning that what was 24px in my 1920 x 1080 mockup, is now 12px on their 1440 x 900 screen.
Is this correct? And if so, is there any solution to this, aside from redesigning the whole site in 1440 x 900?
To further complicate things, what if I have multiple customers with multiple screen resolutions reviewing the same design? I can’t desig a separate file for each individual screen resolution?!
